LAMINATED WEAR-RESISTING COMPOSITION.

Application filed September 29, 1923. Serial No. 665,549.'

To all whom t may concern.'

Be it known that I, JULIAN S'rnzYozKow- SKI, a citizen of the UnitedStates, residing at New York, county of New York, and 6 State of NewYork, have invented certain new and useful Improvements in LaminatedVear-Resisting Compositions, of which the following is a specification.

The principal object of this invention is 10 to provide a new andimproved construction of a composition of matter especially adapted forsuch uses as fioorings, automobile tires and similar purposes where amaterial is required that will stand up under hard and continuous usage.

Another object is to provide a laminated construction of metallic andfibrous material which will form a compact, but semi-resilientstructure, in which the metallic elements are constructed and arrangedto act as a binder or connecting means for holding the fibrous elementsjoined together.

For the accomplishment of these and such further objects as willhereinafter be apparent to those skilled in the art to which thisappertains, the invention consists in the construction, combination andarrangement of parts herein specifically described and illustrated inthe accompanying' drawings, wherein is shown a preferred embodiment ofthe invention, but it is to be understood that changes, variations andmodifications may be resorted to which fall within the scope of theclaims hereunto appended.

In the drawings forming a portion of this specification y Fig. 1 is alplan view of a composition embodying my invention and Figs. 2 and 3 aresections on the lines 2 2 of Fig. 1 and 3-3 of Fig. 2 respectively.

As shown in the drawings, my improved composition consists of aplurality of comparatively thin sheets 10 of a suitable semiresilientsubstance such as fibre, wood, paper, pressed pulp, rubber, canvas orthe like. Between t e sheets 10 a metallic structure 11 is arrangedwhich isl preferably of open mesh configuration as shown in Fig. 2 ofthe' drawing. The strands 12 of the metallic mesh are preferably flat asshown and are formed into a diamond shape mesh, the flat faces of thestrands being twisted to extend transversely of the sheets 10 be tweenthe pointed ends 13 and 14 of the diamonds. At the point of connection15 of the diamond shape meshes, the strands also eX- tend transverselyto the sheets 10. It will be noted that the diamond shaped meshes arearranged in staggered relation between the sheets 10 so that the centrallongitudinal diagonals of the meshes of one metallic structure are inalignment with the points of connection 15'of the adjacent structure. Bystaggering the meshes of the metallic structure in this manner, the endsof the metallicvs'trands which project to resist the wearing strains aredistributed vmore thoroughly and the binding or holding effect of thestrands is also more evenly distributed.

After the sheets 10 and metallic structure 1l are assembled they aresubjected to pressure which causes the flat strands 12 to be pressedinto the adjacent sheets, thus caus ing the strands to erform aneffective binding function and t iereby hold the composition in acompact unitary mass.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. A laminated wear resisting compositionconsisting of a plurality of thin sheets of semi-resilient material andan open meshed metallic structure interposed between said sheets, saidmetallic structure formed of a plurality of interconnected Hat strands,the fiat faces of which extend transversely of and are sunk into saidsheets, to l bind said sheets4 and metallic structure into a compactunitary mass. v

2.. A laminated wear resisting composition consisting of a plurality ofthin sheets of semi-resilient material and a plurality of an opendiamond meshed metallic structures interposed between said sheets, the

meshes of adjacent members of said metallic structures being arranged`in staggered relation.

3. A laminated wear resisting composition consisting of a plurality ofthin sheets of semi-resilient material and a plurality of metallicstructures interposed between ture into a compact mass, and the meshessaid" sheets, said metallic structures being of adjacent members of saidmetallic strucformed of a plurality of flat strands intertures beingarranged in staggered relation. l. connected to form open diamond shapedVIn testimony whereof I have aixed my 5 meshes, the fiat faces of saidstrands, exsignature.

tending transversely to and being sunk into said sheets to bind saidsheets and struc- JULIAN STRZYCZKOWSKI.
